X, Z or U, W defines the end point of arc. It can be described with the absolute or the incremental
coordinates. The incremental coordinate is the distance from the starting point to the end point of
arc.
I, K define the center coordinates: I, K separately correspond to X, Z coordinates, and are the
vector of starting point as the origin pointing to the circle center. It is X component (with diameter)
and K is Z vector. The direction of I, K is the positive /negative when it is the same time as X, Z
positive/negative direction as Fig. 7:
Fig. 7 Circle center coordinates
I value is the diameter. Generally, the counted value of drawing is the radius which must be
multiplied 2 in programming. Use R to program without I, K.
The feedrate of clockwise interpolation from A to B is 100 mm/min as Fig. 8:
